screen shot of "reclaim disk space" panel

anaconda crash in "reclaim disk space" panel for lvm partitions (f23 ppc64 beta RC1) 
I did following test on ppc64 bare metal.

Three steps test.
First step, install of f23 ppc64 (lvm scheme) using little disk space
- use "Manual partitioning" " to remove all existing partitions
- then use "Click here to create them automatically) " to create new partitions
- then change /home size partitions to 20 GB and update
- run the install

Second step, install of f23 ppc64 (lvm scheme) using the rest of disk space
- use " " to create patitions of second install
- run the install

At this time we have:
[anaconda root@furax ~]# fdisk -l

/dev/sda6       157257728 554287103 397029376 189.3G 8e Linux LVM


Third step, delete partitions of first install to do new install
- I try to remove partitions of first install automatically using "Reclaim Disk Space" 
problem is triggering at this time by a click on one of /boot partitions listed 
in "Reclaim Disk Space" panel.
